Video frame interpolation aims to generate frames between consecutive frames. It has attracted a lot of attention because of its wide applications in video editing [1]}, video generation [2]}, [3]}, optical flow estimation [4]}, [5]}, and video compression [6]}. Consequentially, great progress has been made and many video frame interpolation methods are available [7]}, [8]}, [9]}, [10]}, [11]}, [12]}, [13]}, [14]}, [15]}, [16]}, [17]}.
